Hey Glider Security feature Vista 64 bit
Glider did not know if you knew this about 64bit Vista.

One of the primary benefits of using an x64-based version of Windows Vista is that these versions provide dramatically improved security functionality
when compared to their 32-bit counterparts. Most dramatically, the Windows Vista x64 versions include a new secret security feature called Address
Space Layout Randmonizer (ASLR) that helps eliminate remote system attacks for the first time on the Windows platform. This feature (which was first
disclosed in this very article) ensures that system files load at random (1 in 256) memory offsets at every system boot, compared to previous Windows
versions where system files always loaded to the same offset memory location. Because of this change, most (approximately 99 percent) remote attacks
will simply fail on x64-based Vista versions.
x64 has a minor caveat in that it doesn't support 16-bit apps natively (or maybe at all). Good thing is that few applications run using 16-bit, but do
you know what does? Viruses. (I'll be honest, I read that somewhere, but cannot find the proof on me now. So take that "16-bit virus" comment with a
grain of salt.) And you have to write a separate virus for 64-bit, so some "security via obscurity" thing going on as few people actually have 64-bit,
but that will change.

electronic attacks. (32-bit Vista versions utilize a less effective, software-based version of DEP.) Another unique x64 feature, Kernel Patch
Protection (sometimes called PatchGuard), prevents malicious software from patching the Windows Vista kernel. PatchGuard, Microsoft says, works by
preventing kernel-mode drivers from extending or replacing other kernel services and preventing third-party software from patching any part of the
kernel.

Thanks Stanger.
I had heard something about this but did not know the specifics.
